What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Lum-Tec Eclipse

Owners widely praise the Lum-Tec Eclipse for its comfortable, slim profile and thin wearability, with specific commendations for its beautiful dial, good readability, and bracelet design. The knurling on the crown is also noted as a positive feature. Some owners express concern over the 42mm case size and find the dial's font and indices unappealing, though others appreciate the deep-dish slant. One owner notes a slight gap where the lugs meet the bracelet. The Lum-Tec Eclipse e3 variant features a Miyota 9039 movement, a solid bracelet, a sunburst dial, and exceptionally bright lume. Overall, owners rate the Lum-Tec Eclipse highly for its slim design and attractive dial at its price point.

Gruppo Gamma Field III GMT

Owners praise the Gruppo Gamma Field III GMT for its look and value, with specific mentions of its sandwich dial and comfortable OEM straps. One owner notes incredible quality for the price across their Gruppo Gamma watches. The watch features a 40mm brushed stainless steel case, box sapphire crystal, and a Seiko NH34A movement with a 41-hour power reserve and stated accuracy of -20~+40 s/day. Some find the lack of a date window a drawback for a GMT, and question its differentiation from other NH34-powered watches. On balance, owners and reviewers find the Gruppo Gamma Field III GMT to be a good value with quality construction for its price point.
